PAsrai/ovea SPECIFICATION forming part of Letters Patent No. 398,380, dated February 26, 1889.

Application iiled J une 16, 1888. Serial No. 277,316. (No model.)

To all whom it' ntcoy concern:

Be it known that I, JOHN I. CONNOR, acitizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Pastry-Ovens, of which the following, t-aken in connection with the accompanying drawings, is a speciiication.

The object of my invention is to produce a pastry-oven in which the heat is equally distributed through its center, and in which the contents of one half of the oven can be seen without admitting cold air into the other half.

The invention consistsin arranging in the center off the oven a radiator iitted with a partition and a pipe communicating between the fire-pot and the flue, said pipe being provided with a damper and holes communicating with the interior of the radiator, so that when the damper is closed t-he heat and products of combustion are caused to pass through the radiator, thereby bringing the heat to the front part of the oven,'and should the oven be ioo hot, by opening the damper the heat can pass up the pipe directly to the liuc.

Referring to the accompanying drawings, liigure l represents a perspective view of a pastry-oven embodying my invention. Fi

is a longitudinal vertical section through the same. Fig. 3 is a transverse vertical section taken through the radiator.

The top A, back I3, and sides C'oi.' the. oven consist ol" a doublccasing formed ol;l metal plates a l), with an air-space, D, between them. The front E consists of a single metal plate, and is provided with feed and ash-pit doors c d and registers e. All of the above parts are old and ot well-known construction.

In the center ot the casing I place a radiator, F, consisting of two vertical plates, ff with a space ot' a few inches between them, and through thc radi ator at the rear is [itted a pipe, (i, that communicates at its lower end with the tire-pot or stove K, and at its upper end with the Hue. In this pipe are formed two openings, g g', and in the radiator is sey of which extends out through the front, as shown.

By the radiatorF the oven is divided into two compartments, L M, or, as it were, distinct ovens, although they are both heated by the same fire; and on each side of each compartment I secure angle-irons m m, upon which the shelves n rest. The compartment )I in Fig. I I have shown with the two upper shelves removed. Each of the compartments L M are closed by a separate door, N N', so that the contents ot' one compartment maybe inspected wit-hout admitting cold air into the other compartment.

In operation, when a Iire is first started, the damper J is opened, as shown in Fig. 3, and the smoke and products of combustion pass directly up the pipe G in the direction of the arrows marked I; but when the ire is clear the damper is closed and the heat then passes through the radiator in the direction of the arrows marked 2, the partition II causing the heat to pass tothe front of the oven. y this arrangement the heat is more evenly diffused, and consequently the oven is more evenly heated than with ovens of ordinary construction.

Should the oven become too hot, then the damper J is opened and the heat will pass directly up the pipe G, very little, if any, passing through the radiator. The heat ot the bven is also regulated by the ventilators e e, and by the dampers in the ventilating-pipes P, that pass vtrom the compari ments Il M to the lfiue.

astry-ovcns ot ordinary construction. can be easily a-nd cheaply fitted with radiators constructed according to my invention, and although I have shown and described the oven as adapted to be heated by coal they can be equally well adapted to burn wood.

WhatI claim as my invention ism l. In combination with a pastry-oven, the central vertical radiator, F, provided with the pipe G, having openings g g and fitted with a damper, J, and the partition II, whereby the heat entering the radiator through the 'opening g is caused to pass to the front of the oven and thence back and through the opening g to the iue, substantially as set forth.

2. A pastry-oven divided by a Central vertical radiator, F, into two eompartn1ents,L M, Closed by separate doors, N N in combination with J[he smoke-pipe G, having openings 5 g g and damper J, and the {ire-pot K, substantially as shown and described.

In testimony whereof Ihave signed my name to this specification, in the presence of two subscribing Witnesses, on this 17 t-h day of May,

JOHN P. CONNOR.
